HARRISON, N.J. – With every passing game, it seems like less of a coincidence. The Philadelphia Union are on a three-game unbeaten streak. The starting center-back tandem for all three outings has been Auston Trusty and Mark McKenzie.

The latest test for the pair of 19-year-olds was billed as its toughest yet: in Red Bull Arena, against a host that led MLS in points per game, pitted against one of the most prolific scorers the league has ever seen, Bradley Wright-Phillips. But under the pressure of that situation, McKenzie and Trusty muted the leading scorer in MLS, holding Wright-Phillips without even a shot on target, as the Union claimed a 0-0 draw Saturday night that could’ve been a win if not for wastefulness at the other end of the park.

And with that point came another step in the development of two young players whose talent ceilings seem to be ratcheted up by the day.
